WATER-HEATER.

' SPECIFICATION forming part of Letters Patent No. 767,810, dated August 16, 1904:.

Application filed December 16,1903. Serial No. 185, 130. (No model.)

To all whom it may concern:

Be it known that I, JOHN H. GEORGE, a citizen of the United States, residing at Newark, in the county of Essex and State of New J ersey, have invented and produced a new and original Improvementin Water-Heaters; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to figures of reference marked thereon, which form a part of this specification.

This invention relatesto water-heaters, and particularly to water-heaters adapted to be used over a gas-jet in connection with ordinary kitchen water-tanks when there is no fire in the range, the objects ofv the invention being to facilitate and secure greater economy in the heating of water, to prevent clogging of the waterways or ducts in the heater, to enable the same to be cleaned with greater facility and ease, and to secure other advantages and results, some of which may be referred to hereinafter in connection with the description of the working parts.

The invention consists in the improved water-heater and in the arrangements and combinations of parts of the same, all substantially as will be hereinafter set forth, and

finally embraced. in the clauses of the claim.

Referring to the accompanying drawings, in which like figures of reference indicate corresponding parts in each of the several figures, Figure 1 is a side elevation of a waterheater of my improved construction. Fig. 2 is a horizontal section of the same, taken at line :0, Fig. 1. -Fig. 3 is a vertical section taken at line 3 Fig. 2. Fig. 4 is a detail view showing a portion of the base of the casing of the device. Fig. 5 shows a portion of a certain bottom ring, and Fig. 6illustrates the connection of tubes to their end rings.

In said drawings, 8 indicates the base of the casing, which may be of cast metal and have the shape of a hollow truncated cone.

9 represents the middle portion, which is preferably of cylindrical form, of sheet metal, and adapted to fit closely the upper end of the base 8. Said cylindrical section 9 of the easing extends vertically upward from the base and is capped at the top, as at 10, the cap being provided at the center with a chimney or flue 7, through which the products of combustion from the ignited gas may rise. The cap 10 is removable from the cylindrical section to facilitate examination of the water devices within the casing. Within said sectional casing is arranged the water-heating apparatus comprising a bottom ring 11, which may be centrally open, as at 12, to facilitate the Lip-passage of heated air from the gasburner below. At opposite sides of said ring 11 are lugs or bosses 111, which rest between ribs 112, formed at the upper edge of the base 8 of the casing on the inner side thereof, so as to prevent rotary displacement of the bottom ring 11 with respect to the casing. The said upper edge of the base portion 8 of the casing is notched or recessed between said ribs 112, as at 113, and the lower edge of the middle portion 9 of the casing, which overlaps on the outside of said base portion, is also notched at its lower edge, as at 114, in correspondence with the notches 113 in the base, and because of these notches a faucet 15 nipple 16 to the other boss or lug at the opposite side of the bottom ring, all as shown in detail in Figs. 3, 4E, and 5. By screwing said connections up tight, therefore, the over-- lapping edges of the base portion and middle portion of the casing are clamped firmly against the bosses 111 and a rigid union of the bottom ring and two portions of the casing secured.

The faucet 15 has a flange or shoulder 20 and threaded shank 21, which latter enters the threaded perforation 115 of the bottom ring 11, and thus the faucet has open communication with the interior of the ring, and the water in said ring can be drawn off directly from the heater by simply opening the key 22. The overlapping portions of the base 8 and cylindrical section 9 of the casing extend between the flange or shoulder 20 and the boss 111 on the ring 11, and thus are clamped firmly upon screwing up the faucet.

. The bottom of the base is open to permit the insertion of a gas jet or burner and atmospheric air to support combustion, and apeephole 2 1 is preferably provided, with a gate 25 to cover the same.

At the upper side of the ring 11 is a series of slots or perforations in which are seated the lower ends of a series of flat pipes 13, preferably of sheet metal, which are imperviously connected with said ring. At the tops of said flat pipes, which are disposed radially with reference to the center of the ring, as shown in Fig. 2, is a horizontal fiat reservoir 14, which receives the water from the upright tubes 13. Said reservoir 14 and also the bottom ring 11 are both somewhat smaller in diameter than the casing, and so an annular passage 17 is formed which permits a 110W of the gaseous product of combustion to the chimney; but the up movement is restricted,

so that the heat is largely confined within the casing and communicated to the pipes and water therein.

At the top of the reservoir 1 1 is a central threaded bushing 18, to which a hot-water pipe 19, communicating with a boiler or other receptacle in any usual manner, may be connected.

It will be noted that the tubes 13 do not project at their ends into the chambers of the bottom ring 11 and top reservoir 11; but the said ends are inserted in the slots and their edges 131 bent outwardly apart against the edges of the slots or openings, imperviousness being then being secured by brazing or the like. Thus the chambers of the reservoir are free and clear of any obstruction such as might tend to interfere with the ready removal of dirt or the like, either by the flow of water or by mechanical means. Furthermore, upon cleaning the tubes 13, as hereinafter described, any cleanings therefrom will drop freely into the bottom ring and be washed out of the fancet 15 by flow of water.

The threaded bushing 18 at the top of the upper reservoir 14 overlaps in plan the tubular passages 13 or is near enough alinement with them to permit a stick, wire, or other cleaning implement to be thrust down into said tubes. Thus a thorough cleaning of my device can be effected upon simply removing the cap 10 and disconnecting the hot-water pipe 19, allowing a little water at the same time to run through the bottom ring 11 and out at the faucet 15. Obviously this is a great convenience and saves expensive overhaulings.

Various modifications from the exact details of construction positively described may be made without departing from the spirit and scope of my inventionas, for instance, the tubes 13 may deviate slightly from a true vertical and still be within the meaning of the term upright asI have used itand 1 therefore do not wish to be understood as limiting myself except as the prior state of the art may require. v f

Having thus described the invention, what I claim as new is- 1. The improved water-heater herein described, comprising a casing having an open bottom and a chimney at its top, a hollow ring set in said casing, an annular series of vertical flattened tubes each in communication with said ring and having its longest diameter in cross-section arranged in a radial line of said ring, a reservoir at the top of said tubes, an inlet in connection with said ring, and a detachable exit in communication with said reservoir at a point central with respect to said series .of tubes, whereby upon removing said exit a cleaning implement can enter said tubes.

2. The improved water-beater, herein described, comprising a sectional casing having an open bottom and a chimney or vent for the products of combustion'at the top, a hollow ring set at the base of said casing, a faucet leading from said ring and casing, a reservoir at the top of said casing, an annular series of flattened tubes extending from the ring to the reservoir, each tube being arranged with its longest diameter in cross-section disposed in a radial line of the ring, and said ring and reservoir having, respectively, means for inlet and exit of water, substantially as set forth.

3. The combination of the bottom ring 11, having threaded perforations at opposite sides, upper and lowercasing-sections overlapping at the sides of said ring and having their edges notched to register with said perforations, and a faucet and inlet-pipe, respectively, having nipples passing through said notches and being screwed into the perforations to clamp said casing against the bottom ring.

4. The combination of the bottom ring 11, having bosses 111, at its opposite sides, provided with threaded perforations, upper and lower casing-sections notched at their edges in registration with said perforations, the lower section having shoulders to engage opposite sides of said bosses, and a faucet and inlet-pipe, respectively, having nipples through said notches and being screwed into the perforations to clamp said casing against the bottom ring.

IIS

5. In a water-heater, the combination of a bottom reservoir having an inlet at one side and a faucet at the opposite side, upright tubes connecting at their lower ends with the top of said reservoir without projecting into the chamber thereof, a top reservoir similarly connecting at its bottom with the upper ends of said tubes and having at its top an opening permitting access of a cleaning implement to said tubes, and a flow-pipe connected to said opening of the top reservoir.

6. In awater-heater, the combination of top and bottom reservoirs, each providing a free unobstructed interior chamber, a series of tubes, said openingbeing smaller than the circle determined by the outer edges of said I5 tubes but adapted to permit access of a cleaning implement to said tubes, and means for supplying and discharging Water to said reservoirs.

In testimony that I claim the foregoing I 2 have hereunto set my hand this 10th day of December, 1903.
